Let this XP serve as a notice that Matt Bowen is doing an outstanding job at Bleacher Report on this NFL 101 series. He's breaking down common routes and coverage concepts while also delving into keys.

This hit the outtakes of my Factors post, but there was one particular Andre Johnson v. Richard Sherman route that was head-and-shoulders above anything else I'd seen while charting wideouts. Two masters of their craft. Brett Kollman at Battle Red Blog took it upon himself to look at it.
